Abstract: ABSTRACT OF THE DISCLOSURE        In a color photographic material wherein by color development there are produced either non-diffusing image dyes or diffusing image dyes (the latter being transferred to an image-receiving layer) the color development is controlled by means of non-diffusing thioether compounds which on color development release a diffusing mercapto compound but do not themselves form a dye.  The mercapto compound inhibits the development of the silver halide and the thioether compound has the formula   R1 =  hydrogen or alkyl with 1-3 carbon atoms R2 =  alkyl with up to 22 carbon atoms an aralkyl group or an aryl group, and the group -S-Y is split off during color development and forms a mercaptane, e.g. 5-mercapto-1-phenyltetrazole, which inhibits the development.

Abstract: PROCESS FOR RECOVERY OF CARBONACEOUS MATERIALS FROM SUBTERRANEAN DEPOSITS BY IN SITU PROCESSING            ABSTRACT OF THE DISCLOSURE Subterranean carbonaceous deposits, such as oild shale or the like, that are located at or close to the surface, are prepared for retorting by drilling blast holes from the surface into the deposit, and blasting, creating a rubble pile that reaches the surface. The surface is sealed by suitable means, and the oil shale is retorted in place. Where a stratum of barren rock lies between the carbonaceous deposit and the surface, the blast holes are drilled and blasted in such a manner as to maximize the fragmentation of the carbonaceous deposit, and minimize the fragmentation c& the overlaying barren stratum. Where overburden conditions are not suitable for treatment by this method, the overburden is removed by strip mining methods, and the carbonaceous deposits are exposed for treatment by the method described above.

Abstract: ABSTRACT OF THE DISCLOSURE             A fluid motor having a housing with a stepped bore for retaining a first piston and a second piston.  A sleeve is located in the stepped bore to permit the first piston and the second piston to be of substantially the same diameter.  A plug attached to the housing holds the sleeve in the stepped bore.  A spring attached to the sleeve holds the first piston against a stop. The spring acts on the sleeve to create a gap with a shoulder in the stepped bore.  The second piston which is connected to the first piston through a linkage mechanism carries a concentric shuttle piston.  The shuttle piston is subjected to a first hydraulic pressure created by the first piston and to a second hydraulic pressure created by the second piston. An indicator is connected to the shuttle piston and remains inactive when the first and second hydraulic pressure are substantially equal.  However, when-ever the second hydraulic pressure moves the second piston against the sleeve sufficiently to close the gap, the shuttle piston moves to generate a signal which actuates the indicator to inform the operator of such a condition.

Abstract: Abstract of the Disclosure An improved sheet feeding mechanism for an automatically driven typewriter.  The feeder mechanism includes a housing which is mounted on the typewriter and defines a supply magazine for storing a stack of sheets to be typed and a finish magazine for storing typewritten sheets.  When it is desired to feed a sheet through the platen of the typewriter, a platen clutch is dis-engaged to disconnect the platen from the typing mechanism and connect the platen to a feed roll.  A pressure plate is actuated to force the pack of sheets in the supply magazine against the feed roll, and the feed roll will scrub the outermost sheet from the pack and move the sheet downwardly through a tapered chute and around the platen.  After passing around the platen, the leading edge of the sheet actuates a sensing mechanism to release the pressure plate and engage the platen clutch to thereby begin the automatic typing on the sheet,  When the typing is completed, the platen clutch will be disengaged and the sheet is driven up-wardly to the finish magazine, and when the trailing edge of the sheet passes the sensing mechanism the pressure plate will be actuated to feed a second sheet to the platen.
